From the ink you've never seen and the surprising person who was with him when he got his first tattoo (the Libra sign on his wrist) to why he won't be getting another anytime soon, Josh talks all about his tattoos.

"I got my first tattoo when I was 17—I was filming Red Dawn in Detroit, and my mom was with me! She's a very cool mom."

So about the two you can't see...

"My other two tattoos have much less meaning. One is a giant anchor on my side—I've just always liked the classic old-school sailor tattoos. And I have a similar one that's a ship sailing into a sunset with classic birds and lavender clouds on my back."

And why three's the charm...

"Covering them up for the movie is such a pain. If I'm going to have my shirt off in a scene, it means an extra hour-and-a-half in hair and makeup to cover the tattoos on my side and my back."
